Dynamic Halter Top Dress

For use with Poser 5 and Poser 6

Here are some notes on how I set up the figure and dress to obtain the classic Marilyn Monroe scene from the 7 Year Itch...

Tutorial by Phil C. of www.philc.net

This Dynamic Clothing prop has been created to fit the Poser 5 "Judy" figure.

Installation Instructions

First Download the Zip file (at the bottom of the page)

Extract the files to your Poser folder. i.e. the directory where you have Poser.exe installed. Then by selecting "use folder names" in WinZip, files will be correctly positioned automatically.

If you prefer to do it manually the files should be placed thus:

TEMPLATE.jpgProgram Files/Curious Labs/Poser 5/Runtime/Textures/PhilC
Dress.pp2Program Files/Curious Labs/Poser 5/Runtime/Libraries/props/Dynamic Clothing/PhilC Designs
Dress.pngProgram Files/Curious Labs/Poser 5/Runtime/Libraries/props/Dynamic Clothing/PhilC Designs
ALL other filesProgram Files/Curious Labs/Poser 5/Runtime/Read Me/ (These are the instructions)

It is the file path "Runtime" and below that is important. Using Winzip it will look like this:-

To use the dress

Here are some notes on how I set up the figure and dress to obtain the classic Marilyn Monroe scene from the 7 Year Itch.

Where screen shots have been reduced to fit into the text you may click on them for the full sized image.

Start by loading Judy into the scene. Turn her IK chains off using the Figure menu. Open the Joint Editor and click on the zero figure button. Select her hip and set x, y & zTrans to zero.

From the Prop library load in the dress. Your screen should resemble the screen on the right.

Because this is a smart prop and has already been parented to the figure, and because we will later be using a "drape from zero pose" feature, it is not essential to initially pose the figure this way, although I prefer to do so to enable me to check that the dress fits right to begin with. If any part of it is touching the figure at this stage it will result in problems later.

With the dress selected the next operation is to add a wind force and pose the figure. The wind force amplitude is set to vary over a 90 frame animation to give the updraft effect. Changes in expression were also added at this stage.

Note that the figure's zero pose as shown above was just to check positioning it does not form part of the animation.

Setting up a new simulation.

The default simulation range is 1 - 30, edit this if required.

Remember the more cloth collision options you select the longer the processing times. Optimum selections will vary with different situations.

It may be best to start with just the default, and add more if required.

Cloth draping allows the dress to settle prior to the actual animation. I made this dress deliberately flared so that when it draped there would be some realistic folds produced. Too few frames and the cloth will not have settled enough, too many and you are wasting time. I've found that between 15 and 30 frames is a good rule of thumb.

Clothify (what a great word :) the dress.

Define the actor or actors you want the dress to collide with using the Add/Remove button. The more you add the longer the processing time. Note: that if any parts are set invisible they will be ignored by the calculation. i.e. if you were to turn the hip and thighs off then the dress would fall straight through them. Leave them on for the collision calculation but you can turn them off later when it comes to rendering.

Collision Offset:- Increasing will make the dress stand further away from the skin.

Collision Depth:- Higher will give the effect of thicker cloth.

Static friction:- Higher will make the cloth tend to stick to the body more.

Dynamic Friction:- Once the dress material has started to slip over the skin this dial tells it how easily it will continue to slide.

We need to check the "start draping from zero pose" because our animation starts with the figure bent forward. Poser will calculate the "frames" that get the dress and figure from their zero poses to the start of our animation.

The other check boxes are self explanatory. If the dress is not going to hit the head then there is no need to include it in the calculations.

Defining Cloth Groups.

For this particular dress I wanted to ensure that the waistband stayed in place. I also found that I needed to "pin" the rear part of the halter to prevent the weight of the front of the dress pulling it too far forward.

Clicking on the "Edit Constrained Group" button brings up the group editor. I predefined the belt material and added it using the Add Material button. The vertices at the back of the neck were added using the "+" tool. Note that you are adding vertices rather than the polygons that you may be familiar with from the Poser 4 Grouping Tool.

You will find these groups already defined in the Halter Top Dress. Poser saves them as part of the prop file.

Dynamics Controls.

For this scene I wanted the dress to appear to be of a relatively light material so I set the density to 0.0010.

Once set I went back to the Simulation Setting button and calculated the drape, then to the Calculate Simulation button to let it do its thing.

Most of these are self explanatory. If you need to see the different effects try setting up a scene in which the high resolution plane falls over a sphere. I suggest you make changes to one dial at a time or else you may not see what adjustments did what.

Finally the scene was rendered out in AVI format and converted to a Windows Media file using Windows Movie Maker. This is included in the ZIP file you downloaded for the costume.
